- Counting: The child learned to count the number of cards in the deck.
- Matching: The child learned to match pairs of cards with the same number or picture.
- Number recognition: The child learned to recognize numbers on the cards.
- Visual discrimination: The child learned to distinguish between different suits and numbers on the cards.
For continued development, the child can be encouraged to play more matching games with different sets of cards, such as letters or shapes. They can also be challenged to sort the cards by suit or number, or to create patterns with the cards. Additionally, the child can be introduced to simple addition and subtraction by counting the total number of cards and then removing pairs from the deck.
